All point to these facts: Last week, the Tucson Unified School District trustees voted 4-1 to suspend its Mexican American studies classes, as state Superintendent John Huppenthal vowed to pull about $5 million in state funding. In all, the district potentially could have lost more than $14 million, according to news reports.

Huppenthal had found the Tucson classes in violation of a new Arizona law prohibiting ethnic studies. The AP reported that all students were transferred to other courses.

Opponents continue to argue against the controversial law, as they did against the state’s immigration law known as SB 1070. A group is suing Arizona in federal court, arguing that the ethnic-studies law is unconstitutional and violates the First Amendment.

On Friday, the district announced that it has not banned any of the books from the Mexican-American studies courses, though the Arizona Daily Star reported that seven books were removed from school circulation. They are: “Critical Race Theory” by Richard Delgado, “500 Years of Chicano History in Pictures” edited by Elizabeth Martinez, “Message to Aztlan” by Rodolfo “Corky” Gonzales, “Chicano! The History of the Mexican American Civil Rights Movement” by Arturo Rosales, “Occupied America: A History of Chicanos” by Rodolfo Acuña, “Pedagogy of the Oppressed” by Paulo Freire and “Rethinking Columbus: The Next 500 Years” by Bill Bigelow.

The same report said a teacher allegedly had been asked not to teach William Shakespeare’s “The Tempest,” in which the central character enslaves indigenous people, “because it has race and oppression as its central focus,” said the teacher’s attorney.
